There is uncertainty because there are multiple plausible theories, that both come with some arguments, but none are proven beyond reasonable doubt. And according to the method of hyperbolic doubt, if there is reason to doubt, there is uncertainty. And if there's uncertainty, there's no way to tell exactly.Vicsun wrote:How can you tell, exactly?

I think you can find the political motive for stimulating pro-CO2-research in a more abstract commodity than just money: Power. (Money is power, but money is ony a means)
As it is, the western world is dependant upon the Middle East and, increasingly, Russia. We (the western world) can't live without oil and gas, which means we're at these foreign countries' mercy. 'They' have power over 'us' and that goes beyond money. Although the blow that the western world will have to endure when the oilflow is stopped, because we failed to appease one of Arabia's wishes, for instance, will be far stretching, again financially.
And the message that these populist environmentalists bring is: stop using fossil fuels, because they will melt the earth. Well isn't that convenient?
Firstly, the real influence of CO2 on global warming is debatable, as the documentary clearly shows. Is it even true that any of our CO2 is heating the globe, or how damaging is the warming caused by CO2, if there is the case of CO2 accelerating global warming?
But also: what will happen when the underdeveloped countries start to successfully tap into their fuelreserves, specifically Africa? It will lead to a lot more competition in the oilmarket, because it stands to reason that Africa will sell much cheaper, as it desperately needs the money, which significantly decreases the influence of the current oil-magnates in Russia and the Middle East, which means even they have an interest in stopping the expansion of their market.
It is of vital importance for African countries, if they will want to be competitive players in the global market, to use their subterranean, cheap, abundant energy sources, but will they be able to do that if the western world tells them not to, or else..? And that makes the CO2 debate a question of development, because Africa is not in a position where it can afford scientific solutions that even the western world fails to apply effectively, which is mainly because of the cost of these "clean solutions".
So secondly, when you have that in mind, how can you want to enforce a theory that not all scientists agree on and that puts a brake on the development of countries which are relatively poor, who could really use the money and industrial progress? A case of keeping the poor poor so the rich can remain rich?
Obviously, for the countries that CAN afford clean high-tech solutions, the only sensible thing to do is invest big in those clean alternatives, because the oil-shackles are no good. But then let that be the reason, not one that limits world-wide use of a fine energy source.
And I don't want to say that every scientist that gets paid is a dishonest scientist, but you'll have to consider who pays them to do what. And in this case, politicians pay them to prove CO2 emission is bad for the world, to gain independance that is lost through foreign oil and gas and to put pressure on underdeveloped countries to use technologies that they can't afford. (the latter is brutal, at least, and IMO unacceptable as long as the theory justifying it is not undeniably undoubtedly true. EDIT: and it's just as much a doom-scenario as the global warming theory itself..)
